A skydiver is in a plane flying at a constant velocity. If the skydiver is trying to land on a target on the ground, should he jump from the plane when he is directly over the target?
Why or why not?

No,it is not possible to jump directly because the upper body parts are In motion but legparts directly comes in rest due to unbalanced inertia he may get hurt so..

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
